genus Omphalia near Namcho Lake, in Tibet, and gives also a 
note on Estheria as occurring in the Gondwana formation. 
Mr. Lydekker describes certain new and other vertebrates 
from Indian tertiary and secondary rocks, such as Bos acutifrons 
and planiprons , Bubalus platyceros, Stegodon ganesa (which 
elephantoid, like the allied S. insignis , lived down to the Ner- 
budda period, and must have been contemporary with the early 
human inhabitants of India), Sivalhippus Theobaldi (an aberrant 
horse from the Siwaliks), Ictitherium Sivalense, Hycenarctos 
Sivalensis, and certain Saurians, including the new genus 
Titanosaurus. 
Part 2 comprises an account of the rocks of the Lower 
Godavari ; notes on the Atgarh Sandstones near Cuttack ; a 
paper on the Fossil Floras of India ; a notice of some new or 
rare Mammals from the Siwaliks ; a note on the Arvali Series in 
North-eastern Rajputana ; and an account of some borings for 
coal, which describes the cost of the operation and the time con- 
sumed in perforating different rocks, but omits to state whether 
coal-beds were reached, and, if so, what were their thickness and 
quality. 
There is subjoined a paper on the geology of India, which the 
late Dr. Waagen, formerly palaeontologist to the Survey, had 
contributed to the “ Zeitschrift der Deutschen Geolog. Gesell- 
schaft. The author pronounces his opinion that the peninsula 
of India belonged to a great continent, which probably included 
China, the (Malayan) Archipelago, and Australia, perhaps even a 
part of Oceania. 
Part 3 comprises “ Notes on the Tertiary Zone and Under- 
lying Rocks in the North-west Punjab,” by A. B. Wynne, illus- 
trated with a geological map of the district. In this region 
occur the celebrated salt deposits of the western frontier and 
certain petroleum springs of no great importance. 
Dr. Feistmantel gives an account of a tree-fern stem from the 
cretaceous rocks near Trichinopoly. 
Mr. W. Theobald treats on the occurrence of erratics, and 
concludes that at one time “ glaciers were ploughing their way 
down the great Himalayan rivers and valleys, to within 2000 feet 
or so of the sea,” whilst the Potwar was one great lake, with an 
exit probably near Kalabagh as now, and into which lake glaciers 
descended, freighted with the debris of the hills of Hazara and 
Kashmir. 
Mr. F. R. Mallet gives an account of recent coal explorations 
in the Darjiling district. The coal found is extremely friable, 
and could not be worked without great expense, especially as the 
Assam coal could easily be brought to the foot of the Darjiling 
hills. 
The same author likewise describes the limestones found at 
Barakar, and some blowing machines used by the smiths of 
Upper Assam.
